Key takeaways
- Micronized Rubber Powder (MRP) is cured rubber hydrocarbon ground to microscopic particle size, far finer than coarse crumb rubber.
- AP Rubber Group produces MRP from 100% TBR tread feedstock, in grades from 80 mesh up to 170 mesh — 180 micron down to 90 micron.
- The ambient grinding line runs de-beading and shredding, fine shearing, multi-stage steel and fibre separation, then precision air classification.
- Tyre makers can substitute 5% to 15% of virgin polymer in sidewalls, treads and inner liners without losing tensile strength or flex fatigue resistance.
- Main applications are tyre compounding, asphalt and bitumen modification, polymer compounding, and coatings and sealants.
- Grade names state the particle size in MICRONS, not the mesh count: AP MICRORUB 90 is the finest of the five, on a 170 mesh sieve.
As global tire manufacturers, compounding units, and infrastructure projects face rising raw material costs, sourcing high-quality elastomeric raw materials is vital. AP Rubber Group is a premier Micronized Rubber Powder Manufacturer, Supplier, and Exporter, providing high-purity recycled rubber powder solutions engineered to optimize compounding costs without compromising performance.
Whether you require standard mesh grades or the ultra-fine TBR Tread Based Micronized Rubber Powder at 170 mesh, our MicroRub range spans 80, 100, 120, 140 and 170 mesh sieves — 180, 150, 125, 105 and 90 micron respectively — and delivers consistent particle sizing with maximum rubber hydrocarbon content.
What Is Micronized Rubber Powder (MRP)?
Micronized Rubber Powder (frequently called MRP Powder or ultra-fine Rubber Powder) is a cured rubber hydrocarbon processed into microscopic dimensions. Unlike coarse crumb rubber used for basic surfacing, high-grade MRP Powder features extremely fine particle sizing, low fiber contamination, and controlled surface chemistry.
As a dedicated Rubber Powder Manufacturer, AP Rubber Group processes 100% Truck Bus Radial (TBR) feedstocks. This ensures our natural rubber powder and synthetic polymer blends retain the high elasticity and strength inherent in original commercial tire treads.

Why Choose TBR Tread Based Micronized Rubber Powder?
Not all recycled rubber is created equal. As a specialized TBR Tread Based Micronized Rubber Powder Manufacturer, we utilize high-tensile truck and bus tire treads to achieve superior material properties:
- High Rubber Hydrocarbon Content — TBR treads contain premium grade natural rubber and butadiene rubber for heavy load durability.
- Low Ash & Impurities — Clean extraction ensures minimal metal or fiber content (<0.01%).
- Enhanced Polymer Dispersibility — Finer mesh sizes allow rapid dispersion into rubber compounds during mixing cycles.
Our Manufacturing Capabilities: Up to 170 Mesh
At our state-of-the-art facilities — including AP Rubber Industries (Haridwar, India) and AP Recyclers SFZ LLC (Oman) — we operate advanced ambient grinding lines.

Key Applications of MRP Powder
Rubber Powder for Tyre Manufacturing & Compounds
As a trusted MRP Powder Manufacturer, we supply major tire OEMs and retreading plants. Using our Rubber Powder For Tyre Manufacturing and Rubber Powder For Tyre Compounds allows factories to substitute 5% to 15% of virgin rubber polymer in sidewalls, treads, and inner liners without sacrificing tensile strength or flex fatigue resistance.
Asphalt Modification & Bitumen Binders
Fine Tyre Tread Rubber Powder acts as an elastomeric modifier in bitumen for road construction, improving resistance to rutting, thermal cracking, and traffic wear.
Reclaimed Rubber & Polymer Compounding
Our fine reclaimed rubber powder mixes efficiently into thermoplastic elastomers (TPEs), polypropylene (PP), and natural rubber powder formulations to produce impact-resistant molded parts, gaskets, and seals.
Coatings, Sealants & Construction
Incorporating 140 mesh rubber powder into architectural sealants, waterproofing membranes, and roof coatings enhances flexibility and weather resistance.

Frequently asked questions
What is the difference between Micronized Rubber Powder and crumb rubber?
Particle size and purity. Coarse crumb rubber is above roughly 1,000 microns and suits surfacing work. Micronized Rubber Powder is ground far finer - down to 90 microns on a 170 mesh sieve - with low fibre contamination and controlled surface chemistry, which lets it disperse into rubber compounds during mixing.
How much virgin rubber can MRP replace in a tyre compound?
Typically 5% to 15% of the virgin rubber polymer in sidewalls, treads and inner liners, without sacrificing tensile strength or flex fatigue resistance. This is where most of the 15% to 30% reduction in compounding batch cost comes from.
What mesh grades of MRP are available?
Five grades: AP MICRORUB 180 on an 80 mesh sieve, 150 on 100 mesh, 125 on 120 mesh, 105 on 140 mesh and 90 on 170 mesh. The grade number is the particle size in microns, so the finest powder carries the smallest number and the largest mesh count. 80 to 100 mesh is the standard fine powder for asphalt modification and moulded rubber items; 140 and 170 mesh are the ultra-fine grades for high-grade tyre compounds, retreading and masterbatches.
Where is Micronized Rubber Powder used besides tyres?
As an elastomeric modifier in bitumen for road construction, improving resistance to rutting and thermal cracking; in thermoplastic elastomers, polypropylene and natural rubber formulations for impact-resistant moulded parts, gaskets and seals; and in architectural sealants, waterproofing membranes and roof coatings.
